Title (EN) SYSTEMS AND METHODS FOR PERFORMING MULTI-LEVEL CODING IN A DISCRETE MULTITONE MODULATION COMMUNICATION SYSTEM
(FR) SYSTÈMES ET PROCÉDÉS POUR EFFECTUER UN CODAGE MULTI-NIVEAU DANS UN SYSTÈME DE COMMUNICATION À MODULATION MULTITONALITÉ DISCRÈTE
Abstract:
(EN) Embodiments described herein provide a method for performing multi-level coding in a discrete multitone modulation (DMT) communication system. A plurality of data bits are divided into a first number of un-encoded bits and a set of bits to be encoded. The set of bits to be encoded are encoded into a second number of encoded bits. The first number is different from the second number, and the first number is an even number or an odd number. The first number of un-encoded bits and the second number of encoded bits are mapped into a plurality of constellation points. The plurality of constellation points are transmitted as orthogonal frequency-division multiplexing (OFDM) symbols.
(FR) L'invention concerne, dans des modes de réalisation, un procédé de codage multi-niveau dans un système de communication à modulation multitonalité discrète (DMT). Une pluralité de bits de données sont divisés en un premier nombre de bits non codés et un ensemble de bits à coder. L'ensemble de bits à coder est codé en un second nombre de bits codés. Le premier nombre, qui est différent du second nombre, est un nombre pair ou un nombre impair. Le premier nombre de bits non codés et le second nombre de bits codés sont mappés en une pluralité de points de constellation. La pluralité de points de constellation sont transmis sous la forme de symboles de multiplexage par répartition orthogonale de la fréquence (OFDM).
